    I took some user comments way to seriously and figured out what it would take to melt obsidian and sand cast it into a sword.

                        The best attempt would be if the mixed obsidian would be cooled slow. I meant really slow... Just throwing an idea out there

                                  I figured melting the obsidian and cooling it would have it re solidify as a different style of rock just because it takes special conditions for obsidian form and I feel like with all the flux and extras you were throwing in it would make it cool as something else

                                                        so why did they make obsidian very durable in Minecraft?
